Metabolite Identification
Common NameOripavine
DescriptionOripavine belongs to the class of organic compounds known as morphinans. These are polycyclic compounds with a four-ring skeleton with three condensed six-member rings forming a partially hydrogenated phenanthrene moiety, one of which is aromatic while the two others are alicyclic. Oripavine is a very strong basic compound (based on its pKa). The simple bridged oripavine parent compound 6,14-Endoethenotetrahydrooripavine is already 40 times the potency of morphine, but adding a branched tertiary alcohol substituent on the C7 position results in a wide range of highly potent compounds. Outside of the human body, oripavine has been detected, but not quantified in, several different foods, such as radish, cocoa beans, black radish, alpine sweetvetchs, and rocket salad. This could make oripavine a potential biomarker for the consumption of these foods. Replacing the N-methyl group with cyclopropylmethyl results in opioid antagonists such as diprenorphine (M5050, which is used as an antidote to reverse the effects of etorphine, M99), and partial agonists such as buprenorphine, which is widely used in the treatment of opioid addiction. Due to its use in manufacture of strong opioids, oripavine is a controlled substance in some jurisdictions. Oripavine possesses an analgesic potency comparable to morphine; however, it is not clinically useful due to severe toxicity and low therapeutic index. It is the parent compound from which a series of semi-synthetic opioids are derived, which includes the compounds etorphine and buprenorphine. On September 24, 2007, the Drug Enforcement Administration formally added oripavine to Schedule II.Under the Controlled Substances Act 1970, oripavine has an ACSCN of 9330 and a 2013 manufacturing quota of 22,750 kg (50,160 lb). Oripavine has a potential for dependence which is significantly greater than that of thebaine but slightly less than that of morphine. Oripavine is an opiate and the major metabolite of thebaine. Of much greater relevance are the properties of the orvinols, a large family of semi-synthetic oripavine derivatives classically synthesized by the Diels-Alder reaction of thebaine with an appropriate dienophile followed by 3-O-demethylation to the corresponding bridged oripavine. This molecule is biosynthetically related to the morphinane derivatives metabolism, where thebaine and morphine are implicated. These compounds were developed by the group led by K. W. Bentley in the 1960s, and these Bentley compounds represent the first series of "super-potent" μ-opioid agonists, with some compounds in the series being over 10,000 times the potency of morphine as an analgesic. On March 14, 2007, the United Nations Commission on Narcotic Drugs formally decided to accept these recommendations, and placed oripavine in the Schedule I.Until recently, oripavine was a Schedule II drug in the United States by default as a thebaine derivative, although it was not explicitly listed.
